What is Mastodon?
Mastodon describes itself as a “free, open-source decentralized social media platform.”
Mastodon’s homepage
It has microblogging features like Twitter but on a decentralized infrastructure named the fediverse (or federated universe). Although it sounds very much like Web3, it is only similar and not exactly the same.
Mastodon is free for the average user, but as always things are a bit more complicated which I will elaborate on below.
